Hello,
it seems that you have configured msilo to notice the sender that the
destination is offline. If the contact used by serweb points to server
itself (I guess is daemon@), then there will be a loop that will get
accounted but msilo will ignore messages coming from/going to registrar
address (so you get: MESSAGING: offline message NOT stored). You should
have some specific processing logic for these special addresses (if uri
== daemon@ || sip_registrar@ => drop) in your config file.

Hey list,
Think I’m finally making some progress with msilo and serweb
messaging. Things appear to work, but when I look in the logs I see
some interesting things. The relevant bits of code are shown at the
bottom.
Basically what I see from the logs is that when a UA is ONLINE, but
Doesn’t support messaging, I correctly see:
(i.e the failure_route[1] seems to pick it up).
Jul 21 16:55:03 sip /usr/sbin/ser[20927]: MESSAGING: Destination UA
does not support MESSAGE requests. Stored.
In the log file. However, it is immediately followed by: (161.30.94.68
is sip.dev.inmarsat.com – its not in DNS yet)

Jul 21 16:55:03 sip /usr/sbin/ser[20924]: MESSAGING: MESSAGE to
offline user received -> storing using MSILO
i.e. then something happens which makes Ser process it again as a
message to an offline user. I don’t understand this. Is it something
to do with the way that serweb sends messages? Perhaps something
related to this sip:daemon@... address? Does Ser try and send it
internally? And is my logic then confused by the internal ACK’s?
Any help would be very very much appreciated.
Thanks again,
Dave
